Well, what I was thinking of doing is having UV orange tubing, but with UV blue liquid flowing through it. In which case, the surround edges of the tubing would glow orange, but a bright blue would theoretically be showing in the center of the tubing. They'll both be in one loop, but two different UV colours that would (hopefully) show.

Unless you had a tube in a tube, then you might possibly see the different coloring, but one would have to be much more reactive then the other. Maybe they make a chameleon type UV reactive that can change depending on the light being shone into it?

Nah, I don't think there is. I've been looking high and low for information on it, but seeing how scarce it is, I'm assuming it's not doable.

In any case, I think I know what I'm going to do: Strategically put orange LED's in the forefront of the case to shine off the tubing, and have UV lights in the background to cause the UV blue liquid to glow. Not sure how well it'll work, but I think that's the best option I have to get something similar to what I want. Worse comes to worst, I'll just ditch one of the two LED's and call it a day
